Something is wrong with my head today xD The link is here

It depends on the version your using.

AS2:
public hitTest(x:Number, y:Number, [shapeFlag:Boolean]):Boolean

AS3:
public function hitTestPoint(x:Number, y:Number, shapeFlag:Boolean = false):Boolean

And while Dank very neatly pointed out the testing against a certain point (which is useful as well, don't get me wrong!) I get the idea you're looking for a collision between two objects - which is both in as2 and as3 something like this:
mc1.hitTest(mc2); (as2)
mc1.hitTestObject(mc2); (as3)

thx alot i appreciate it

Could someone explain the collision code to me?

Which code exactly, SB? >.>"

well that's all fine and dandy code dank and pixelsmash but that will only check collisions of the bounding boxes... so if you have 2 circles (or anything else non-rectangular for that matter) colliding it will detect collisions where there very clearly is none. There's a nice workaround posted here:

how can you make a movie clip change when collision happens?

there are many different ways to do this

one is to edit mc1 so it has 2 frames in it each with different image. then add stop(); to the first frame in mc1. then when i collides with mc2 add this code.

mc1.gotoAndStop(2);

so it would be like
{
mc1.hitTest(mc2);
mc1.gotoAndStop(2);
}
?

yes
